New ad from GOP gov group hits Gov. Scott Walker's opponent

As promised, the Republican Governors Association is on the air in Wisconsin with an ad slapping down Mary Burke, Democratic challenger to incumbent Gov. Scott Walker.

The ad hits Burke for her tenure as Commerce secretary under Walker’s predecessor, Gov. Jim Doyle, holding her responsible for job losses during his 2006-2010 term. It also criticizes her family business, Trek bicycles, for manufacturing most of its bikes in China instead of the USA. Burke “would take Wisconsin backwards,’’ the ad says.

Last week, the RGA told The Washington Post it would spend six figures on the Wisconsin ad. The GOP group also launched an ad against Arkansas Democrat Mike Ross, a former congressman running in an open-seat gubernatorial race, tagging him as a big spender. Former representative Asa Hutchinson and businessman Curtis Coleman are seeking the Republican nomination.
